Hello,
I've just released gnutls 3.1.4. This release includes initial support for the DTLS-SRTP protocol contributed by martin Storsjo updates on the new DANE library, and several simplifications on the existing API.

Version 3.1.4 (released 2012-11-10)

libgnutls: gnutls_certificate_verify_peers2() will set flags depending on the available revocation data validity.
